session-reader-plugin

In multi-session workflows, an agent in one conversation often needs to inspect another session's context to continue a discussion, and without cross-session read access this means manual copy-paste. session-reader-plugin lets an agent read other DSH sessions directly, in a strictly read-only and bounded fashion. Core capabilities include the session_list tool (enumerate sessions by id, workspace, or archive status) and the session_read tool with four modes — io (messages and tool calls/results), thinking (reasoning chunks), surface (post-compaction model-visible messages), and raw (pre-compaction event stream). The plugin also ships /sessions list and /sessions read slash commands that produce output without consuming a model turn, making them ideal for scripted queries. Built as pure JavaScript with zero native or build dependencies, it activates automatically once installed alongside DSH. It is a natural fit for power users juggling concurrent sessions, multi-step automation pipelines that need contextual continuity, and anyone looking to break down information silos between conversations.
